TEMPORARY LOSS OF POWER

Chevrolet Other

I have a 1992 Chevy Cavalier with around 79,000 miles on it. Background info: the car was previously owned by a man who drove the car only 3000 miles over the last 7 years and then hit a small tree dead center in the front end of the car, causing the hood to be slightly raised, but it still latches properly. It kind of looks like it's popped all the time, due to the wrinkles that have formed from wind or whatever getting under it.
First problem was a dinging noise, like a reminder noise if you leave your lights on, that only happens when it rains or snows. It will ding until the car comes to a complete stop, then it will stop. Sometimes it will start again, stopping again when the car stops again. Annoying. But then the horn stopped working, and there is not a burnt out fuse. Then, since it has started snowing, sometimes when I start the car after it has been sitting for a long time, it will immediately stall and all the presets on my radio are lost, like the battery is dead. But then it will start right up and act fine, until the next time I go to start it. I have checked the connection of the cables to the battery, and they are tight. I don't know that these things are related, but I am most concerned about the seeming battery problem.
Could it be due to the moisture getting under the hood? If so, short of getting a new hood and the dent pulled out, what could I do?
Thanks.

It sounds like it is definity mousture related. The stall is most likely a faulty connection to the alternator/ or the thing itself (ice on brushes?). As for the reminder noise. It sounds like mosture shorts that wire. Mosture under the hood is bad for the wireing and accesories. Thats why your getting gremlins. But. Freezing is bad. So check the battery for a fault. Otherwise it is up under the console on the ignition wires. It may also just be a cold weather problem.I wouldn't know in So Cal

I found and removed the speaker under the dash that was causing the dinging and discovered the problem. The part where the box plugged into a little fuse panel had been water corroded. My next question is what are the other 2 fuses on that panel supposed to do, because i'm guessing they may now get wet? Where can I find a diagram identifying the fuses? My owner's manual is missing, so I don't know if the info would've been in there.
